I don't have that much experience using paint - still learning to draw, and it looks like it is going to take many more years before I achieve any proficiency with it. Thus far I have noticed that black can easily turn one's colours to mud. Nevertheless, I like it when used judiciously. A really pitch black can sometimes give a sort of velvety sheen to a picture that it would otherwise lack, or so it seems to me.
